[Resolved]Mefisto Mesh Fails in Current Master-BUG

[quick61]

Just a check before a bug report. Mefisto mesh is failing in Mesh Design Workbench.

Steps to reproduce. Make simple shape in Part Workbench, (Cube will do). Go to Mesh Design WB. Select the Cube, (or whatever shape you made), and activate Meshes > Create mesh from shape... Select Mefisto and click OK.

Code: Select all

MEFISTO_2D failed on subshape #3 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 0"
MEFISTO_2D failed on subshape #13 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 0"
MEFISTO_2D failed on subshape #23 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 0"
MEFISTO_2D failed on subshape #27 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 0"
MEFISTO_2D failed on subshape #31 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 0"
MEFISTO_2D failed on subshape #33 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected. Address 0"

A Mesh object is created in the Tree, but the Mesh Part is not displayed in the 3D view. Can anyone else confirm with daily PPA or self compiled current master?

I tested this two days ago under Ubuntu 12.04 and had no crash at all.

No, there is no crash, just a failure to produce a mesh part, and the string of error messages in the Report view.

C offers greats ways to shot oneself in the feet. I still wonder why it did not generate compiler warnings, for implicit casting of pointer types. But at least i got some practice using gdb

shoogen, wmayer, thanks for fixing this! Nice job, Mefisto Meshes are working once again.

Hi, hope someone will see this even if this thread is old. I have the same problem, but I can not find the file to edit since i do not have that directory.
Can you tell me where i can find it?

Hi @SaMTem and welcomed.

If you are experiencing the same problem upgrading to latest production release should resolve the problem. As this issue was fixed in the past.
